The hills are the most decisive factors how the settlements followed the landscape. But three more defining feature I found:
1. actual beaches, that gently sloping into the water
2. rivers
3. open flatland
Now I have to note, now these settlements aren't necessarily "fishing" ones, despite the boats. At some google explicitly wrote it is. Or at least the port is for fishing boats.
Here are some types I found representative:
#1 This is similar to this >>50443, where the houses follow the shore on a longer distance, in a couple houses depth, occasionally a road leading inside depending on the size of the village.
#2 The houses are bunched up in a valley at a narrow beach.
#3 The valley/s offer flat lands where they can cultivate rice or some such.
#4 More often then not a stream or river will run in the main valley, offering more space to build and for cultivation.
